TO. ALI.. WHOM IT MAY CONCER:

v .'Be it known that I, F. THIRY, lof Huy, in' Athe Kingdom of Belgium, have invented a new and improved Apparatus for Paper-Making vMachines and other Machines having Travelling-Websand Fabrics; and I do hereby declare `that the following isa full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference beingr had to the accompanying drawings, forming part of this specification. I v

The object. of this iuvention'is to restore the endless cloth or wire, on which the Apulp or paper travels, (in the manufacture of paper, and thewebsor fabrics in other manufactures,) to its true course, when, from any cause, it has a tendency to depart therefrom; and tothis end I use a self-acting guiding-apparatus, as hereina-ftcr fully shown and described. In the'accompanying. sheet of drawings- Figure 1 is a side view of my invention. I

`Figure 2 a plan or top view-of the same,- and Figure 3 an end view of the same.

Similar letters of reference indicate corresponding parts.

' In the manufacture of paper, the endless cloth or wire en whichthe pulp or'paperis supported during its progress through the niachine, passes over a guide-roller. This cloth is liable to displacement during'the working of the machine moving either tothe one side or the other outof its proper. path, unless means be used to retain itin or restore it to itsproper position.

By my within-described invention the cloth or web may be guided in a true position, `or immediately restored to such position', whenever it departs therefrom. v l

'The conducting-roller A, shown in red in al1 the gures of tliedrawing, is supported at one end of the movable bearing B, its other end resting in a fixed bearing. The web or cloth C, shown, in blue in figs. 1 and 2, passes over this roller, forming a broken line, and givingv arotary-uition to a roller.' D, shown red, is a wooden rule, which is supported at one end by a lever, E, and atthe other end by al lever, E', (seemore particularly iig. 2.) On this rule D there are tted two -metal blades or plates-F, (I prefer copper.) .Between these plates F the web or cloth passes, as shown at iig. 2. -A small crank, G, on one of the journals of roller A,lg. 2, serves to impart motion to thelever H,-which carries a forked leverf'I, (figs. 1, 2, andai) J is a Whee1,(5ee morePm" ticularly iig. 2,) which is toothed onV both its faces, so that thevforked'lever I may'catch therein, as required.

Under these .arrangements the web or endless cloth cannot displaceitself without carrying with it the rule D,

which, by the aid of the double-branched lever E, 2, causes the forkedv or. curved lever to -catch in the wheel .T on one of its faces. -K'is a screw, having a left-hand thread, andon which the wheel J is keyed or otherwise secured, and it will be observed that on'the combinedinotion of the rule-leversE, I, and J, the screw receives a rotary motion, and thus throws the guiding-cylinder or roller A out of square to the right or left, in the direction of the displacement of the web or cloth, and this change of position inthe cylinder prevents further displacement of the web or cloth. p i

It should be particularly observed that the conducting-roller displaces as it were itself, 'the displacement being caused by the 'self-action of the apparatus previouslydescribed; and it should also be remarked that the conductingroller can' only displace itself in equal ratio with the displacementof the web or cloth, as the forked or curved lever I -doesnot follow the rectilinealmovernent of Vthe apparatus wheuworking, being restrained by the lever E, which only receives motion on anydisplacement-of the web, andfrom the web itself. The apparatus releases itself, the lever I-being disengaged-from the toothed wheel J, by the displacement of the conductingrollcr this being essential to success; otherwise the apparatus would continue to act, and cause'co'ntinual i' displacement of the web or cloth.

The two hooks, L, (see iig. 1,) serve'torestrain the apparatus at either endo its course,'a's one or the other of them meets with the head of the bearer M, (figs. 1 and 2,) which arrests it, ud thus prevents the lever I Having thu's described my invention, I claim as new, and desire to secure 'by 'The rule D, provided with the plates FiF, and conneeted'to the levers E E', in co K, double-too`thed wheel J', curved lever I, lever H, and crank G, on one ofthe journals of @ducting-roller AA, all arranged to operate in the manner substantially as and for the purpose herein set forth.
